    Arrow crazy bump alternative

    im sure that there are a lot of you who have used crazy bump
    and the time limit ran out and you found your self limping a bit.
    well even though the price is well worth it, there is a cheaper alternative

    free even if you dont mind a little work.

    http://www.shadermap.renderingsystems.com/

    the pro is 20 dollars us
    and they even provide a non commercial command line version that does the same as the graphical one.
    which is free.

    all you have to do is dload them both (not huge)
    and use the gui to preview and adjust until you get it just right.

    them transfer those settings to a batch file to call the command line version.
    and viola(?)
    you have the textures you see and crave from your diffuse original.

    they provide example batfiles to get you going and the online doc is good.

    anyway thought i would share
    later.

    Theres also a free very advanced mapper called mapzone http://www.mapzoneeditor.com/ , and is quite easy. Might not be as easy to use as crazy bump , but you can do alot more with more features in this programe than crazy bump. I think this is the best programe for mappers. on the site theres also good tutorials to get you started. for a programe to be such versatile and advanced , I am surprize its free , so you can spend a couple hundred dollars on crazy bump or get this better programe for free. I am not trotting down crazy bump , it is a good mapper programe , I just dont agree with the price.

    How about xNormal? Not merely cheaper, but free.

    ZBrush has the best normal mapping app, xNormal & crazy bump suck after you master ZB

    And how much does Zbrush cost? I think the point of the thread isn't to find the best (no matter the cost), just one that works well that's free.

    On that note, I started using GIMP, just wondering if there is a way to create normal maps with it?

    Yes there is , and there is a normal mapper plugin for it. It is good , it is called free normal map http://developer.valvesoftware.com/w...on_in_The_GIMP . theres also a free normal map program called normal map compressor http://www.codeproject.com/KB/direct...ompressor.aspx , it doesnt have as much features as crazy bump but its the easiest program to make normals with , it also gives you different type of compressions. Theres also the nvidia photoshop plugins , that has a normal map plugin for photo shop

    Thanks for the link. Once I get comfortable with the actual program, I will try to make a normal map for something.

    It's good for generating normals from geometry - still, mostly ogranic - but it sucks if you need to generate normals from the color images. A big number of color images.

    AFAIK CB seems to be the best in terms of ergonomy and speed. The fact, that it's price is so high - comparing to the common price of 30-40 USD for single task application, means that is has no real competition. Keep in mind that CB also generates specular and ambient occlusion maps - even for the normals that were generated somewhere else.

    Rendering ambient occlusion/cavity map maps takes a lot of time, much more that normal maps. Using CB, you can make 2-3 version of these maps in just few seconds. Rendering the same stuff using MR would take much, much longer.

    make your photo into a grayscale image export it as a psd, inport it into ZB as a alpha brush, then make your normal map from that, easy

    True, it can be done but nobody uses zbrush for this purpose because it wasn't designed to do that and second the whole process would be horribly ineffective.

    If you think about alpha-skulpting the plane, there're two problems: you have to manually position that an alpha brush over the plane to not loose (or keep) the texture tiling and the fact that you will have to fix the output image because zbrush have problems with the the UV's set to 0-1. Not to mention that you will have to paint/skulpt the plane of 10-15 mln polys to generate 2048x2048 texture.

    The point it that using zbrush you'll generate a single texture while other people generate 10 using Photoshop, GIMP or CB.
